Top Forums Shell Programming and Scripting Need to generate a file with random data. /dev/[u]random doesn't exist. Post 302845943 by Devyn on Thursday 22nd of August 2013 04:17:21 PM

Thanks very much all for the replies. Really appreciate it. The place to run this for me would be even in basic shells like the Linux, Solaris, AIX etc 'maintenance' / 'recovery' shells.

So things like Perl or openssl won't work as required libraries won't be loaded in those simple recovery shells.

Corona688:
That's a good option there but unfortunately it didn't work fully or I should say it DID work partially. The loop continued to run even though the dd command ended / stopped.

Cheers,
DH

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list. Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1). FILES
